Study the effect of some tooth paste On the oral health

   This study was conducted to investigate the effect of toothpastes used for oral health by acting as antimicrobial against biofilm formations. Different types of toothpastes were selected, including those were made of natural materials and others with artificial chemicals using herbal additives.                      Five tooth pastes (Lacalut®, Paradontax®, Colgate®, Miswak®, Sanino®) were used on microbiota spectrum of spp. Bacteria (s. mutans, s. viridans) obtained by swab plaque accumulated in teeth from different patients over a period of 2021, the exclusion criteria from the investigation were patients receiving concurrent antibiotic treatment for any purpose. This research was conduct in central environmental laboratory at Baghdad University. Each toothpaste is diluted with distilled water to prepare 0.2 and 0.3 concentrations. The estimation of bacterial spectrum was performed in qualitative manner using standard methods for microbiological inoculation tissue plate culture (TPC)were performed (for bacterial presence) and quantitative qualification of the subjects by, Elisa instrument.   It was found that toothpaste which contains natural materials is particularly effective in improving oral health and reducing the incidence of gingivitis caused by microbial bacterial presence. This revealed that the naturally occurrence of different groups of organic compounds flavonoids and phenolic acids (esters), are responsible for many of the biological activities against oral bacteria

Influences of learning styles on learner satisfaction in e-learning environment

E-learning tools as an emerging technology has changed the process of higher education dramatically influencing learners' learning style in various ways. Learning styles is the ways of people learn and it has become an important topic for researchers recently. The main purpose of this research is to analyze influences of learning styles in e-learning environment at universities. This paper will provide an overview of learning styles of different learners based on the knowledge of Felder and Silverman learning style model based on the survey conducted using the different type of learners in the university E-learning environment. Further, this paper proposes a developed framework of the E-learning environment of higher education students
